Analyzing Z370 for Intel's 8th Generation Coffee Lake: A Quick Look at 50+ Motherboards
by Ian Cutress, Anton Shilov, Joe Shields & Gavin Bonshor on October 20, 2017 2:00 PM ESTASRock Z370 Taichi
In a board that stands in the ASRock's 'upper mid-range' class on its own, the Taichi name lives on another generation in the Z370 Taichi. As with those that came before it, Taichi boards are aimed to be balanced, and do not show a propensity to lean in any which way: gaming, workstation, overclocking, it could (like many other motherboards) do it all. The Z370 version won’t stray from that target either.
The Z370 Taichi looks almost the same as its bigger brother on the X299 platform. The same cog or gear artwork is featured prominently in grey against the all black PCB. The back panel and audio section are covered with the same style shroud from the X299 Taichi. The large VRM heatsinks from the Gaming i7 and Gaming K6 also find their way to the Taichi but in black instead of grey. The chipset heatsink, also in the shape of a gear, is the only place on the board to find RGB LEDs. Users are able to add more color via an LED strip through the onboard header.
The four memory slots provide support for 64GB, with speeds up to DDR4-4333. The Taichi has three reinforced full-length GPU slots, capable of x16 in single card, x8/x8 with two cards, and x8/x4/x4 in three card mode, meaning the board supports both 2-way SLI and 3-way Crossfire. There are also two open-ended PCIe x1 slots, powered from the chipset.
The board offers six SATA ports from the chipset, two SATA ports from an additional controller, and three M.2 slots. The bottom two M.2 devices support up to 110mm while the top supports up to 80mm. The slots do share lanes, so that if the first M.2 slot is populated, SATA 0/1 are disabled. If the second M.2 slot is in use, SATA 4/5 are disabled. Last, if the third M.2 slot is populated by a SATA type M.2 device, SATA3 is disabled, so be aware.
The board has five 4-pin fan headers in various locations around the board to allow for BIOS or F-Stream software control in Windows. The CPU Optional and Chassis Optional pumps both deliver 1.5A/18W to the headers, for powering pumps from AIOs or custom built loops. The same audio found on the higher end boards also made it over to the Taichi via the Realtek ALC1220 codec, and uses Nichicon Gold series audio caps as well as a Texas Instruments NE5532 headset amplifier. Two Intel Ethernet controllers, the Intel I219-V and Intel I211-AT, and an Intel W-Fi module, make up the network side. As with nearly all the ASRock boards, Thunderbolt support is handled by a 5-pin add-in-card connector.
USB connectivity on the back panel IO consists of a USB 3.1 (10 Gbps) Type-A port and Type-C port from an ASMedia ASM3142, as well as four USB 3.1 (5 Gbps) ports from the chipset. A front panel USB 3.1 (10 Gbps) header is found internally, along with three USB 2.0 headers (chipset) and two more USB 3.1 (5 Gbps) headers (ASM1074 hub). The remainder of the back panel IO contains a Clear CMOS button, a combination PS/2 port, DisplayPort and HDMI, and audio jacks plus SPDIF.

Excellent summary and table in the last page. Good work!!!imaheadcase - Saturday, October 21, 2017 - link
I got a few questions:1. Why do they put USB 2.0 ports if USB 3.0 is backward compatible anyways? Why not just all USB 3.0 ports..it can't be price.
2. Why do they have such a vary in memory timings? For %99 of people memory timings are not really a big deal right? Maybe in old PC days it was.
3. Mini-ITX vs Micro-ITX..isn't it silly both exist in first place? Any reason for this..the diminsions are really close to the same. In fact, most Micro-ITX is simply removing lots of stuff from mobo that you really want to begin with.

I'd imagine they want to offer as many ports as they can without taking away too many PCIe lanes. The other option would be to embed a USB 3.x switch (or a PCIe switch) but of course now each port wouldn't simultaneously be able to operate at peak speed and 3.x switches are probably more expensive than USB 2 controllers.imaheadcase - Sunday, October 22, 2017 - link
Ahh didn't think about that aspect.DanNeely - Saturday, October 21, 2017 - link
Some USB audio and 2.4ghz wifi/bluetooth devices have had interference problems in 3.0 sockets. Dunno if they're fixed on new hardware (supposedly onboard hubs were a lot worse than chipset ports in this regard so room for QC to make it better); but even if they are there's going to be problems with once burned customers not trusting them.As pointed out elsewhere USB3 competes with PCIe lanes/SATA ports on the southbridge. Especially on full ATX boards if you go to max out the number of PCIe lanes to expansion slots and m.2 ports in addition to the lanes used on board for networking and audio you can get down to only a half dozen or so 3.0 lanes left from the chipset; but still able to hit 14 USB ports total by going USB2 with the rest.
People using older OSes (Windows 7 says hi) can't use USB3 ports to install the OS without jumping through a lot of hoops (the OS sees them as not USB2 and can't talk to them).
If any board size is at risk of going away it's probably full ATX; although for enthusiast sales I suspect it'll hold on better than mini ATX due to bigger is better irrationality.
MiniITX still has a decent capability gap vs mini ATX; but it's much smaller than it was a half dozen years ago when it only made sense if you were making a tiny box and were willing to accept major performance compromises to do so. Now as Mini ITX's capability continues to goes up and the need for expansion cards other than a single GPU goes down it's eating into an increasing chunk of Mini ATX's marketshare.
On the high side mainstream chips don't really have enough PCIe lanes to make good use of the extra 3 cards of space possible on the bigger boards/ Meanwhile multi-GPU gaming - the main reason an enthusiast would need a full size mobo is steadily going away (fewer games supporting it each year, no support for 3/4way at all in the newest cards from either company); and unless you need 2 GPUs + something else or extra space around the CPU for crazy OCing Mini ATX does almost everything that could be needed.

> If any board size is at risk of going away it's probably full ATX; although for enthusiast sales I suspect it'll hold on better than mini ATX due to bigger is better irrationality.Irrationality indeed. I would have thought by now instead of a measly 5 mATX choices out of 50+ that it would be instead maybe 5 fullsize ATX with the main battleground being the two slot mATX market.
Its just laziness on the manufacturers side, with nobody steering the market to innovate on size. Theres nobody driving form factors, the CPU companies are present on all form factors so they dont need to drive change, the board partners are all set in their ways just slapping new images on mildly reworked designs so they dont have any need to innovate, weve seen video card manufacturers can shrink designs to better fit smaller factors but we still get chunky easy to produce cards for mainstream use as retooling would be an added cost, its just rolling train of new but nothing new generation after generation.
PC design is falling into mediocrity and I just wish the main players (intel+amd/board partners/nvidia+amd) would all get together to drive SFX/ITX and force retire ATX to the strictly enthusiast market, and maybe appeal to a more contemporary home user community (rather than just gamers which is where the marketing all seems to be these days) again too.

It is really true that the MSI PC Pro has a legacy PCI connector? I could use this for my TV tuner. But I thought PCI was not supported by newer boatds/CPU`s?Morawka - Saturday, October 21, 2017 - link
Has anyone noticed how cheap these new Z370 motherboards are? Most are under $180 and there are several sub $130.IGTrading - Sunday, October 22, 2017 - link
Tell this to the guys that already spent money on non-Z370 just a few months ago.Intel is already screwing them.
It would have been funny to sell a 250 USD motherboard to a 7700K buyer just last month, telling him his 250 USD are a good investment because of the good upgradeability.
Just 4 weeks later tell him: "Well ... Yeah ... About that upgrade ... It will cost you a minimum of 110 USD extra + the 360 USD for the new 8700 K.
775 was the last good & long lived platform from Intel.

If people brought Z370 boards expecting them to support an additional CPU generation, they did it in spite of every Intel CPU release for the last decade: two CPU gens socket generation. There's no counter to ignoring the past.
